Hey, speaking of Xv... I've noticed that when I run with Xv enabled, and I quit a program that uses the tuner (xawtv, radio, etc), the audio keeps on going. When I disable Xv, the audio stops correctly along with the video.
So, when I have Xv enabled, if I want to get the audio to stop, I have to do a xawtv -noxv, and then quit again.
Ever run into that?
